Puerto Rico: San Juan and the Castillo San Cristóbal

Puerto Rico is one of several places I need to get back to at some point. There’s so much to see on that island that a day of exploring during a cruise doesn’t even nearly do it justice.

The Castillo San Cristóbal, originally built by the Spanish to protect San Juan from attack, boasts an excellent view of the sea. It’s also a great place to see some centuries-old graffiti made by prisoners. You can read more about that in the post I did on historical graffiti, which I’ll link to here.

Gaffiti from prisoners thrown into this tiny dungeon, centuries agoIn case you wondered what the tiny room behind the iron bars was. Also, I need this sign for my office.

While I’m fairly certain that there are no whales in this photo, my wife did spot some in this area shortly before this picture was taken.
